I am wondering if you folks have any suggestions for sanding and
finishing epoxy resins after they are pored and cured. I am pouring
epoxy mixed with dry pigments into silver frames allowing it to
harden. I want to create a mat finish to get rid of the “plastic
look”. I tried using#600 wet/dry sandpaper over the entire surface
and this transferred silver dust to the epoxy. I had heard somewhere
that there are papers specifically made for plastics. Any suggestions
would be very much appreciated.
